My folks' place in Franfurt is about 2 blocks away from the Sudbanhof, so it's one of the first spots that Greg and I photographed. Originally, we were hesitant to do much walking around on the tracks but once Greg went back to the states, I got bored. And with no one around to say "hey, maybe that's not such a great idea," I did a lot more exploring that took me closer to um, moving trains.
